Eternal Lifet: I Rely on Fortune Points for Improvement

Jiang Feng was trapped inside the Divine Sect's residence. He discovered that the outside was full of Divine Sect disciples, and that going out would surely mean certain death.

For safety's sake, he decided to stay hidden and not go out. The longer he could hide, the more luck points he would gain.

More than two years have passed in the blink of an eye. The disciples of the Divine Sect outside thought that Jiang Feng had died inside. Unexpectedly, the accumulation of luck points over the past two years has allowed Jiang Feng's cultivation to break through once again.

This is a rather cowardly and cunning novel, with a well-developed plot and intelligent supporting characters.

This book is also known as "The Immortal Little Jailer".
